mu4e does not list all messages in INBOX [closed]

Question

I have installed and configured mu and mu4e as explained in the manual (newest version on emacs 24.3.1). My mu4e config contains:

(setq mu4e-maildir "~/Maildir/mail_user_de")

(setq mu4e-drafts-folder "/Drafts")
(setq mu4e-sent-folder   "/Sent")
(setq mu4e-trash-folder  "/Trash")

These folders exist and each contains three subfolders: cur, new and tmp. When I fire up mu4e it says:

[mu4e] Started mu4e with 4023 messages in store

however, when I enter the INBOX folder, there is no mail listed. On the other hand, when I enter the last 7 days bookmark, all emails from the last seven days are listed.

My assumption is, that mu4e does not care for emails which have been downloaded outside of emacs because

1. When I update (calling offlineimap and mu index) within mu4e the email are sorted correctly into the INBOX
2. When I update outside of emacs, the mails are listed in the bookmark but not in the INBOX until they are marked read outside of mu4e. If this happens outside of mu4e they will not show up in the INBOX, otherwise they will suddenly appear (flagged read) in the INBOX.

Obviously I don't like this. I would prefer if all mails, independent whether they were downloaded from within mu4e or directly in a terminal, show up in the INBOX. Is this a bug or a feature (which, so I hope, can be disabled)?

Answer 1

I ran into something similar. I suspect it's because I had mu index ~/Maildir rather than ~/Maildir/mail_user_de (using your setup as an example), but I haven't checked. Regardless, the following change worked for me:

(setq mu4e-maildir "~/Maildir")
(setq mu4e-drafts-folder "/mail_user_de/Drafts")
(setq mu4e-sent-folder   "/mail_user_de/Sent")
(setq mu4e-trash-folder  "/mail_user_de/Trash")
